RESUMEN
In countries endemic for liver and GIT diseases, frequent emergency department (ED) patients contribute to a disproportionate number of visits consuming substantial amount of medical resources. One of the most frequent ED visits is patients who present with hypovolemic shock, abdominal pain, or confusion with or without signs of upper gastrointestinal bleeding (UGIB). The use of conventional two-dimensional ultrasound (2D-U/S) may provide immediate and useful information on the presence of esophageal varices, gastrointestinal tumors, and other GIT abnormalities.The current study investigated the feasibility of using (2D-U/S) to predict the source of UGIB in ED and to determine patients' priority for UGE.Between February 2003 and March 2013, we retrospectively reviewed the profiles of 38,551 Egyptian patients, aged 2 to 75 years old, who presented with a history of GI/liver diseases and no alcohol consumption. We assessed the value of 2D-U/S technology in predicting the source of UGIB.Of 38,551 patients presenting to ED, 900 patients (2.3%), 534 male (59.3%) and 366 female (40.7%) developed UGIB. Analyzing results obtained from U/S examinations by data mining for emergent UGE were patients with liver cirrhosis (LC), splenomegaly, and ascites (42.6% incidence of UGIB), followed by LC and splenomegaly (14.6%), LC only (9.4%), and was only 0.5% who had no morbidity finding by 2D-U/S.Ultrasonographic instrumentation increases the feasibility of predictive emergency medicine. The area has recently not only gained a fresh impulse, but also a new set of complex problems that needs to be addressed in the emergency medicine setting according to each priority.

A correct preoperative definition of the hepatic duct confluence anatomy of right liver living donors is a pivotal step in determining their candidacy for donation and planning the surgery. The purposes of this study are to evaluate the accuracy of three-dimensional Magnetic Resonance Cholangiography (3D MRCP) when compared with intraoperative cholangiography (IOC) in assessing biliary anatomy and to identify imaging characteristics that may help predict the yield of hepatic duct orifices in the right liver graft. Twenty consecutive right liver donors were imaged with 3D MRCP and IOC. The MRCP and IOC findings were compared, and the results confirmed against actual donor anatomy. Three-D MRCP accurately predicted the biliary anatomy in 18 of 20 cases. Specificity and positive predictive value of 3D MRCP in defining normal biliary anatomy was 100%. In 2 patients, 3D MRCP failed to indentify abnormal anatomy. The yield of more than one hepatic duct was associated with: (I) The presence of abnormal biliary anatomy, (II) The length of the main right hepatic duct, and (III) The presence of an acute angle at the confluence of right and left hepatic duct. In conclusion, 3D MRCP reliably represents normal biliary anatomy. The presence of anatomical variations decreases MRCP sensitivity and makes IOC or duct probing a necessary tool for accurately performing the transection of the right hepatic duct.
